DESCRIPTION:

The IDT49FCT805/A and IDT49FCT806/A are clock

drivers built using advanced dual metal CMOS technology.

The IDT49FCT805/A is a non-inverting clock driver and the

IDT49FCT806/A is an inverting clock driver. Each device

consists of two banks of drivers. Each bank drives five output

buffers from a standard TTL compatible input. The devices

feature a "heartbeat" monitor for diagnostics and PLL driving.

The MON output is identical to all other outputs and complies

with the output specifications in this document.

The

IDT49FCT805/A and IDT49FCT806/A offer low capacitance

inputs with hysteresis.

Rail-to-rail output swing improves

noise margin and allows easy interface with CMOS inputs.
